Fedotowsky and Martinez met on the reality show “The Bachelorette” but have called time on their romance.

An insider said, “Ali Fedotowsky and Roberto Martinez have ended their relationship,” and went on to add, “As they go through this difficult time, we ask that you respect the couple’s privacy.”

Roberto, 28, proposed to Ali on the season finale of 2009’s sixth season of “The Bachelorette” and the couple were engaged for 18 months before going their separate ways.

The couple were waiting to marry so they could get to know each other better. Ali explained the delay, saying, “We didn’t meet in the most traditional way. We had a very short courtship and we only knew each other nine weeks before we got engaged. We are still figuring out our lives as individuals.”

But it appears things weren’t quite peachy in their relationship. An insider reveals, “Their relationship has been tumultuous since day one. They’re either extremely happy or they can’t stand each other.”

Another source close to the couple said, “They bring out the worst in each other. She’s miserable in the relationship and he is too.”
